Jarrah Timber Flooring and Decking

Eucalyptus marginata is one of the most common species of Eucalyptus tree in the southwest of Western Australia. The tree and the wood are usually referred to by the Aboriginal name Jarrah.

Jarrah was once called Swan River mahogany after the river system that runs through Perth.

The tree grows up to 40 metres high with a trunk up to 3 metres in diameter, and has rough, greyish-brown, vertically grooved, fibrous bark.

Jarrah is commonly used for cabinet making, flooring, panelling and outdoor furniture. The finished timber has a deep rich reddish-brown colour and an attractive grain. When fresh, jarrah is quite workable but when seasoned it becomes so hard that basic wood-working tools are useless. It is very durable, even in wet and weathered situations, making it a choice structural material for bridges, wharves, Decking, Flooring.

Jarrah wood is very similar to that of Karri, Eucalyptus diversicolor.

Both trees are found in the south west of Australia, the two timbers are frequently confused. They can be distinguished by cutting an unweathered splinter and burning it: karri burns completely to a white ash, whereas jarrah forms charcoal. Most of the best jarrah has been cut out of south Western Australia. Janka Rating 8.5
